Bitcoin fell over the past 24 hours as traders positioned for a Federal Reserve decision that could break a market pattern dating back more than three decades.

Data from CryptoSlate showed the largest cryptocurrency falling as much as 3% to $62,913, its lowest level in nearly two weeks, before recovering to $63,795 as of press time.

The weakness comes ahead of the Fed's July policy meeting, only the second under Chairman Kevin Warsh. The US central bank has kept its benchmark rate unchanged at 3.50% to 3.75% since December, while President Donald Trump has repeatedly pressed policymakers to lower borrowing costs.

Still, investors largely expect policymakers to leave rates unchanged Wednesday.
